HIGH-LINE CARRIAGE.

Application filed October 19, 1927. Serial No. 227,211.

The present invention relates to a high line carriage particularlyadapted for hauling logs, and has for its prime object to provide astructure wherein it is possible to hoist a log to any convenientheight, and haul the same safely without injury to any surroundingtimber and the like. In the old method of hauling in logs by the highline, the logs moved towards their destination before they had clearedthe ground, causing much breakage and the loss of small trees by thelogs dragging over them. The present invention overcomes theseundesirable features.

A still further important object of the invention resides in theprovision of carriage of this nature which is simple in itsconstruction, inexpensive to manufacture. Strong and durable, thoroughlyeflicient and reliable in operation, and otherwise well adapted for thepurpose for which it is designed.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of the carriage embodyingthe features of my invention.

Figure 2 is a top plan View thereof.

Figure 3 isa vertical transverse section taken substantially on the line3 3 of Figure 1.

Figure 4 is a vertical longitudinal section taken substantially on theline 44 of Fig- Y will be seen that three plates, 5,6 `and 7 are heldtogether in spaced parallel planes by suitable bolts-8 or otherfastening elements. A pair of grooved rollers l Vand plate 6. Thesegrooved rollers 10 and 11 are adapted to ride on the high line 16. Agrooved roller 17 is journaled on the shaft 18 between plates 5 and6below the grooved roller 1() and has trained thereover a pull and hoistline 19 which isl trained under the pulley of the hoisting block 20 andis anchored as at 21 in an arm 22 which is pivoted as at 23. A clutchstructure denoted generally by the letter C comprises a plurality ofblocks 24 with notches 25 therein through which is trained the high line16 between the rollers 10 and 11. These blocks are connected together`at their upper and lower ends respectively by bars 27 and 28. One of theend blocks 24 has an extension 29 with a slot 30 formed therein. The bar28 is extended at the end opposite to the block 24 having the extension29. The extremity of the extended portion of the'bar 28 is pivotcd as at31 to the arm 22. A pin 33 between the plates 5 and 6 extends throughthe slot 30. A shoulder 34 is mounted between the plates 5 and 6 and hasa recess 35 in the lower portion thereof to receive the upper end of theblock 20. Guides 36 are provided to lead the block so that the upper endwill seat in the recess 35. A projection 37 is provided on the upperends of the block laterally thereof and moves in a vertical slot 38provided in the plate 6 extending vertically from the lower edgeythereof. A pair of spaced parallel guides 39 are mounted on the plate 6one to each side of the upper portion of the slot 38. A second pair ofguides 40 are disposed in spaced parallelism onthe plate 6 above theguides 39. These guides 39 and 40 are vseparated by a slot 41 in theplate extending horizontally.

A Z-shaped member 42 is movable between the Guides 39 and 40. A pair ofpins 43 ant 44 project vlaterally from the lower portion ofthe clutchstructure C as is shown to advantage in Figures 3 and 4 and projectsthrough the slot 41 to be disposed one on each side .of the Z-shapedmember 42. The weight of4 this Z-shaped member 42 is sufficient so thatits intermediate portion would .function as a cam lll) when the Z-shapedmember gravitates downwardly and moves the bar 28 to pivot the blocks 24to their locking position as shown in Figure 8. The block with itsprojection 37, however, holds the Z-shaped bar 42 in a raised positionwhen the block is raised. However, as soon as the block lowers, theZ-shaped member tends to immediately lock the clutch on the high line 16so as to prevent any movement of the carriage. It will also be seen thatas the block 20 moves down to the dotted line position shown in Figure5, the cable 19 will pass over the pivot 23 so as to tend to swing thearm 22 to the dotted line position shown in Fig. 5 and further assist inthe locking of the clutch structure.

A latch is pivoted on a pin 51. This latch 50 has pivoted extensions 52and 53 at its ends. The extension 53 is in the downward path oi' theprojection 37 so that in order for the block to lower, it will benecessaryr 'lor the latch 50 to swing to the dotted line position shownin Figure 4. This latch is prevented from swinging to this position bymeans of a bolt 54 slidable in a way 55. This bolt is slidable by oneend of a lever 56 projecting thereinto being pivoted as at 57 and havingits upper eittremity engaged with the pins of the pin wheel 14. Springs58 tend to hold the lever in a vertical position.

A lin'e 59 is attached to a block 2O so as to return the carriage to theposition for engaging the logs. `When in the proper position, the cable19 is slackened thereby allowing the block 24 and simultaneouslyallowing the Z-shaped bar 42 to p ull so that the pinv 44 will tend tolock the clutch and simultaneously the slackening of the cable willallow the.arm 22 to swing over to the dotted line position to which itis urged by the clutch thereby assuring the locking of the clutch.

New the movement of the carriage by the cable 59 rotates the pin wheel14, in Figure 4, in a counter-clockwise direction so that thebolt 52 isslid out of the way of the latch extension 52 soA that the latch 50 mayfit into the dotted line position and allow the block to movedownwardly. When the block is down, and the log is engaged thereon bymeans of a chain or in any other desired manner, the. cable 19 is pulledby a winch or Yother structure so as to hoist the block 20.

As the block moves upwardly into the guides 32 and finally comes vtorest in the shoulder 34 the further pulling of the cable 19 willeausethe swinging of the arm 22 to its full line position therebyreleasing the clutch and simultaneously, the projection 37 will engagethe Z-bar 42 so that the intermediate portion thereof will function asan inclined plane or cam on the pin 42 and will unlock the clutch.

The further pull on the cable 19 will pull the carriage to the left asshown in these drawings which rotates the pin wheel in a clockwisedirection so that the bolt 54 is eX- tended over the latch extension 52so that the block cannot fall as long as the carriage is moved in thisdirection.

It is thought that the construction, operation, utility, and advantagesof this invention will now be quite apparent to those skilled in thisart withouta more detailed description thereof. The present embodimentof the invention has been disclosed in detail merelyby way of examplesince in actual practice it attains the features of advantage enumeratedas desirable in the statement of the invention and the abovedescription.
